Description

BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates in general to the field of security systems. More specifically, the present invention relates to a system and method for mitigating audible acknowledgement volume in a vehicle security system.
2. Description of the Related Art
Remotely locking or securing a vehicle (e.g., enabling the vehicle's alarm system) utilizing a key fob or remote control may produce an audible acknowledgement (e.g., a short honk from the horn) by the vehicle indicating a successful operation has occurred. As well-known to those with skill in the art, the volume of the audible emission is static and set such that it can penetrate a noisy environment and be heard from a distance. However, in some instances (e.g., at night, near a residential area, etc.) the volume of the audible acknowledgement may be a nuisance to the surrounding environment. Therefore, there is a need for a system and method for addressing the aforementioned limitation of the prior art.
SUMMARY OF THE INVENTION
The present invention includes a system, method, and computer-usable medium for mitigating audible acknowledgement volume in a vehicle security system. A preferred embodiment of the present invention includes measuring an amplitude of a value signal, in response to receiving the valid signal; in response to determining the amplitude of the valid signal, comparing the amplitude to a first predetermined threshold; in response to the comparison, adjusting a volume setting of an audible acknowledgement; further adjusting the volume setting in response to measuring ambient noise of a surrounding location; and emitting the audible acknowledgement.
The above, as well as additional purposes, features, and advantages of the present invention will become apparent in the following detailed written description.
BRIEF DESCRIPTION OF THE FIGURES
The novel features believed characteristic of the invention are set forth in the appended claims. The invention itself, however, as well as a preferred mode of use, further purposes and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying figures, wherein:
FIG. 1A is a pictorial representation of an exemplary automobile security system in which a preferred embodiment of the present invention may be implemented;
FIG. 1B is a block diagram of an exemplary automobile security system in which a preferred embodiment of the present invention may be implemented; and
FIG. 2 is a high-level logical flowchart diagram illustrating an exemplary method for mitigating audible acknowledgement volume in a vehicle security system according to a preferred embodiment of the present invention.
 DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Referring now to the figures, and more particularly, referring to FIG. 1A, there is illustrated a pictorial representation of an exemplary vehicle security system 100 according to a preferred embodiment of the present invention. As illustrated, vehicle security system 100 includes a vehicle 102 and a remote control 104. Vehicle 102 incorporates receiver assembly 120, while remote control 104 is implemented by transmitter assembly 121, both discussed in more detail in conjunction with FIG. 1B.
FIG. 1B is a block diagram illustrating an exemplary vehicle security system 100 in which a preferred embodiment of the present invention may be implemented. As depicted, vehicle security system 100 includes a receiver assembly 120 and a transmitter assembly 121 that communicate wirelessly via antennae 138 and 146. Receiver assembly 120 includes ground 122, power supply 124, antenna 138, RF receiver 128, processing unit 130, system memory 132, microphone 136, and speaker 137.
System memory 132 includes volume manager 134 for controlling audible acknowledgement volume, as discussed herein in more detail in conjunction with FIG. 2. RF receiver 128 sends data to volume manager 134 after receiving a valid signal from transmitter assembly 121. Microphone 136 measures the signal/noise ration of the surrounding environment and sends data to volume manager 134.
Still referring to FIG. 1B, transmitter assembly 121 includes ground 140, coin cell (power supply) 142, RF transmitter 144, antenna 146, data processing system 148, and push button switches 150. When a user presses push button switches 150, data processing system 148 determines which button was pressed and sends out the corresponding signal. For example, transmitter assembly 121 may transmit different signals for different functions. A first signal may open a trunk door, a second may unlock the doors, while a third may lock the doors.
FIG. 2 is a high-level logical flowchart diagram depicting an exemplary method for mitigating audible acknowledgement volume in a vehicle security system according to a preferred embodiment of the present invention. The process begins at step 200 and proceeds to step 202, which illustrates volume manager 134 determining if RF receiver 128 has received a valid signal from transmitter assembly 121. If a valid signal has not been received, the process iterates at step 202. If, however, a valid signal has been received, RF receiver 128 measures the amplitude of the signal emitted from transmitter assembly 121. If the amplitude of the signal exceeds a predetermined threshold (step 206), volume manager 134 reduces the volume setting of the audible acknowledgement, as illustrated in step 208. If the amplitude of the signal emitted from transmitter assembly 121 does not exceed a predetermined threshold, the volume setting of the audible acknowledgement will be increased, as depicted in step 210.
The process proceeds to step 212, which illustrates volume manager 134 calculating the proximity signal-to-noise ratio of the surround environment by measuring the ambient noise of the environment via microphone 136. If surrounding area is a noisy area, such that the computed signal-to-noise ratio is above a predetermined threshold, the volume setting for the audible acknowledgement is increased (step 214). Conversely, the surround area is a quiet area (e.g., nighttime or residential area) such that the computed signal-to-noise ratio is below a predetermined threshold, the volume setting of the audible acknowledgement is decreased (step 216). The process continues to step 218, which illustrates volume manager 134 emitting the audible acknowledgement with the calculated volume setting via speaker 137. Finally, the process ends, as illustrated in step 220.
As discussed, the present invention includes a system, method, and computer-usable medium for mitigating audible acknowledgement volume in a vehicle security system. A preferred embodiment of the present invention includes measuring an amplitude of a value signal, in response to receiving the valid signal; in response to determining the amplitude of the valid signal, comparing the amplitude to a first predetermined threshold; in response to the comparison, adjusting a volume setting of an audible acknowledgement; further adjusting the volume setting in response to measuring ambient noise of a surrounding location; and emitting the audible acknowledgement.
It should be understood that at least some aspects of the present invention may alternatively be implemented in a computer-usable medium that contains a program product. Programs defining functions on the present invention can be delivered to a data storage system or a computer system via a variety of signal-bearing media, which include, without limitation, non-writable storage media (e.g., CD-ROM), writable storage media (e.g., hard disk drive, read/write CD-Rom, optical media), system memory such as, but not limited to Random Access memory (RAM), and communication media, such as computer and telephone networks including Ethernet, the Internet, wireless networks, and like network systems. It should be understood, therefore, that such signal-bearing media when carrying or encoding computer readable instructions that direct method functions in the present invention, represent alternative embodiments of the present invention. Further it is understood that the present invention may be implemented by a system having means in the form of hardware, software, or a combination of software and hardware as described herein or their equivalent.
While the present invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention. Furthermore, as used in the specification and the appended claims, the term “computer” or “system” or “computer system” or “computing device” includes any data processing system include, but not limited to, personal computers, servers, workstations, network computers, main frame computers, routers, switches, personal data assistants (PDAs), telephones, and any other system capable of processing, transmitting, receiving, capturing, and/or storing data.
